GATE.

SPECIFICATION forming part of Letters Patent No. 430,610, dated June 24, 1890.

Application filed July 9, 1888. Serial No. 279,351. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN Auesrnnenn, a

citizen of the United States, residing at Trenton, Butler county, Ohio, have invented new and useful Improvements in Gates, of which the following is a specification.

My invention relates to an attachment for gates, to render them self-closing; its object being to supply an independent device applicable to most gates in common use, whereby at little expense and trouble they may be made self-closing.

To this end my invention consistsina stud cast with a plate for its attachment to the flat front face of the gate-bar, by screws or nails, a conical friction-roll to operate on said stud, and a semicircular spiral casting provided also with plates for attachment to the front face of the gate-post, all adapted to be attached to a gate provided with the ordinary vertical hinge-pintles, and to be furnished as cheap articles of manufacture, ready to be applied to gates without special skill or change of other parts.

Mechanism embodying my invention is ex- -hibited in the accompanying drawings, in

which Figure 1 is a front elevation of a gate and gate-post to which my invention is applied;

Figs. 2 and 3, perspective views, respectively,

of the inclined Way and friction-roller with its stud detached; and Fig. 4, a partial horizontal section of the gate and gate-post further showing the relation of the parts in use. Referring now to the drawings, the gate A is attached to the gate-post B by ordinary strap-hinges a, the vertical pintles b of which are somewhat elongated to permit the vertical movement and play of the gate in its gravitating action.

Upon the gate, preferably about midway between its hinges, I attach a friction-roller 0, carried upon a stud 0, held upon a screwplate 0, by which it is firmly secured to the face of the gate A, and in a corresponding position upon the gate-post l3, concentric with the common axis of the pintles b, I attach the semicircular spiral or inclined plane D by means of screws through the fiat ears or lugs d. I prefer to construct the roller 0 in conical form in proper angular relation to the axis of the pintles, so that it will roll without abrasion upon the inclined way, the surface of which has a proper shape to accommodate the conical roller, and rises spirally through an arc of half a circle. The stud with its screw-plate, the conical roller duly perforated, and the spiral inclined way, are each cast complete and require no hand or machine work to prepare them for use. They are provided and sold as articles of manufacture, and the mode of application is so simple as to require only the most ordinary knowledge to fit up a gate complete. In nearly all cases the pintles in common use are sufficiently long to be used without change, but they may, where required, be elongated by any blacksmith.

The action of the device is as follows: In the act of opening the gate, the bearing of the roller upon its inclined way elevates the gate vertically upon its hinge-pintles, and on the release of the gate, gravity, through the opposite action of the elements, closes it and retains it closed. It will be observed that the relation and fit of the parts are such as to retain the roller upon its stud without any fastening device.

I do not herein claim, broadly, the use of a roller and inclined surfaces in connection with the hinge-pintles of gates and similar structures, but confine my claim to the elements described used as separate from the hinges. These devices by their form and mode of application are producible as exceedingly cheap articles of manufacture, and are applicable to existing pintle-gates without special skill or change of parts.

The device is also obviously applicable to doors, shutters, 850.

I claim as my invention and desire to secure by Letters Patent of the United States- A set of castings for a gate, consisting, first, of a stud provided with a fastening-plate, adapting it to be secured to the gate so as to project the stud horizontally and rearwardly beyond the gate at the front face, between the upper and lower hinges; second, a friction-roll adapted to revolve upon said stud; In testimony whereof I have hereunto set third, a spiral inclined way having a fastenmy hand in the presence ot two subscribing :0 :ing plate 01' plates adapting it to be secured Witnesses.

to the front of the ate-11in e post in proper carrying relations to said friction-roll and I JOHN AUGSPURGER' the hinge-pintles, to cause the gate to be ele- Witnesses:

vated thereby in opening, substantially as L. M. HOSEA,
